License: permissive · Maintenance: active · Popularity: top 1,000 on PyPI

## Install

pip install tinycss2

## Description

tinycss2 is a low-level CSS parser and generator written in Python: it can
parse strings, return objects representing tokens and blocks, and generate CSS
strings corresponding to these objects.

Based on the CSS Syntax Level 3 specification, tinycss2 knows the grammar of
CSS but doesn't know specific rules, properties or values supported in various
CSS modules.

## AI interpretation — verify before relying

tinycss2 parses CSS strings into token and block objects and generates CSS from those objects, following the CSS Syntax Level 3 specification without enforcing specific properties or values.

Verdict: tinycss2 is a stable, actively maintained CSS parser suitable for projects needing low-level CSS tokenization and generation. Its minimal dependency footprint, permissive BSD license, and support for current Python versions (3.10–3.14) make it a reliable choice with no known security vulnerabilities.
